DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS

FIG. 1 is a schematic view of a portable electronic device according to the disclosure. FIG. 2 is a partial exploded view of the portable electronic device of FIG. 1 . Referring to both FIGS. 1 and 2 , in this embodiment, a portable electronic device 10, such as a notebook computer, includes a main display 100 and at least one external display 200 (two external displays 200 are shown here as an example). The external display 200 is detachable relative to one side of the main display 100. The external display 200 includes a body 210, a slider 220, a latch 230, and an elastic member 240. The slider 220 is slidably disposed in the body 210. The latch 230 is pivoted to a column 214 of the body 210 and coupled to the slider 220, and the elastic member 240 is connected between the slider 220 and the body 210. After the external displays 200 being assembled to the side edge of the main display 100, the display surfaces of the external displays 200 are substantially coplanar with the display surface of the main display 100 to be extending displays of the main display 100.

FIGS. 3 and 4 are schematic views of assembling a main display and an external display. Referring to FIGS. 2 and 3 first, in this embodiment, the latch 230 includes a pivot portion 231, and a driving column 232 and a tenon portion 233 opposite to each other. The driving column 232 and the tenon portion 233 substantially extend from two opposite sides of the pivot portion 231. The driving column 232 is movably connected to the slider 220, and in particular, is movably coupled to a guiding hole 221 of the slider 220. One end of the elastic member 240 is connected to a boss 215 of the body 210, and the other end of the elastic member 240 is connected to a boss 224 of the slider 220. Furthermore, the slider 220 further has a guiding recess 222, which is formed by a pair of guiding walls 225 and 226, and the body 210 further has a boss 213. The boss 213 passes through the guiding recess 222, so that when the slider 220 slides, the boss 213 may slide along the pair of guiding walls 225 and 226 (and the formed guiding recess 222) to have a guiding effect.

Furthermore, the body 210 further has a pair of hooks 211 and 212 respectively passing through the guiding recess 222, that is, located between the pair of guiding walls 225 and 226. More importantly, the pair of hooks 211 and 212 are slidably locked on the guiding walls 225 and 226 facing away from each other. As shown in FIGS. 3 and 4 , the hook 211 faces toward the left in the figure and is slidably locked on the guiding wall 225, and the hook 212 faces toward the right in the figure and is slidably locked on the guiding wall 226. Accordingly, a corresponding relationship between the hooks 211 and 212, and the guiding walls 225 and 226 may not only generate the guiding effect on the sliding of the slider 220 relative to the body 210, but also provide an effect of limiting the slider 220 in a direction of injecting into or ejecting the plane of the drawing paper because the hooks 211 and 212 are locked on the guiding walls 225 and 226. Accordingly, a corresponding relationship between the hooks 211 and 212, and the guiding walls 225 and 226 may not only generate the guiding effect on the sliding of the slider 220 relative to the body 210, but also provide an effect of limiting the slider 220 in a direction of injecting into or ejecting the plane of the drawing paper because the hooks 211 and 212 are locked on the guiding walls 225 and 226. That is, it is ensured that the slider 220 may be stably attached to an inner surface of the body 210 to move without falling off the body 210, so as to improve a stabilizing effect of a sliding stroke of the slider 220.

Referring to both FIGS. 3 and 4 , the slider 220 of this embodiment further has a pressing portion 223, and the pressing portion 223 protrudes out of the body 210 (as shown in FIG. 3 ) as the slider 220 slides relative to the body 210, or is hidden in the body 210 (as shown in FIG. 4 ). A user is adapted for providing a force F1 to press the pressing portion 223 and push the slider 220 accordingly. At the same time, the driving column 232 is movably coupled to the guiding hole 221, and the slider 220 substantially slides in a vertical direction, while the guiding hole 221 expands in a horizontal direction. Therefore, a linear movement of the slider 220 may drive the latch 230 to rotate relative to the body 210 accordingly, so that the tenon portion 233 is rotated out of the body 210 or hidden in the body 210. Referring to both FIGS. 2 and 4 , the tenon portion 233 that is rotated out of the body 210 may be used to be inserted into and locked in a locking recess 110 on the side of the main display 100. Here, the tenon portion 233 may be locked in the locking recess 110 by a tight-fitting structure.

Referring to FIG. 4 and comparing with FIG. 1 , in this embodiment, the tenon portion 233 that is rotated out of the body 210 is adapted for being inserted into in a forward direction of a direction of gravity G1 and engaged with the locking recess 110 of the main display 100, so that the external display 200 is hung beside the main display 100 by its own weight. The forward direction refers to that an included angle between the tenon portion 233 and the direction of gravity G1 is less than 90 degrees, which is beneficial for the user to hang the external display 200 beside the main display 100 while providing the force F1 to press the pressing portion 223 of the slider 220. Here, the slider 220 may be regarded as moving along the direction of gravity G1 to rotate the tenon portion 233 out, while the elastic member 240 also deforms and accumulates an elastic force due to the relative sliding of the slider 220. When the tenon portion 233 that is rotated out of the body 210 is inserted into the main display 100 to complete the combination by the gravity (the weight of the external display 200), it also means that the tenon portion 233 that is rotated out of the body 210 is required to maintain the state of being rotated out as shown in FIG. 4 . Conversely, when the user detaches the external display 200 from the main display 100, and no longer provides the force F1, the elastic force of the elastic member 240 may drive the slider 220 to reset, and the pressing portion 223 may protrude out of the body 210 again.

It should be further mentioned that, as shown in FIG. 1 , the two external displays 200 are each combined to the main display 100 by the same latching mechanism. However, this embodiment is not limited to the number of the external displays 200 and the positions where the external displays 200 are combined to the main display 100. In addition, as shown in FIG. 2 , a top and a bottom of the slider 220 each have the corresponding latch 230 and the corresponding elastic member 240. Since the structure and the operation mode of the corresponding latch 230 and the corresponding elastic member 240 are the same, the above description is made only with the components at the top. The balance of the components in this embodiment is further considered, and this embodiment is set as shown in FIG. 2 . In another unillustrated embodiment, the slider 220 may be configured with only one corresponding latch 230 and one corresponding elastic member 240, and the operation mode remains the same as described above without changing.

Based on the above, in the embodiment of the disclosure, the external display of the portable electronic device is equipped with a movable latch, and the slider may drive the tenon portion of the latch to be rotated out of the body or hidden into the body while being driven, such that when the tenon portion is rotated out of the body, the external display may be inserted into the side of the main display by the latch, and the external display and the main display may be combined with each other. In this way, the at least one external display of the portable electronic device may be disposed on a periphery of the main display, thereby extending and expanding a display screen of the portable electronic device.
